Meiji Sampler 1.0.0
Meiji Sampler 1.0.0 is the release where the fast terminal sample workflow becomes a complete production sampler. The core loop is still the same: Browse -> Assign -> Loop -> Scene -> Mix. What changed is how far that workflow can now go. You can play Meiji Sampler from a MIDI controller, shape channels with classic sampler character, turn long recordings into playable chops, license Splice sounds through official MCP support, and learn the whole system through the new documentation site. This is a major release for existing users and a cleaner starting point for new users.Highlights
- MIDI controller performance: map external pads, knobs, faders, transport, loops, scenes, mixer mutes, and individual chop slices, with a built-in MIDI Monitor for identifying devices and events.
- Splice support: browse Splice’s growing library of over 2 million royalty-free loops & samples, then license and download with a single keypress.
- Official documentation: structured Start Here, Learn, Guides, Recipes, Reference, Troubleshooting, and Release Notes pages at docs.sampler.meiji.industries.
- Vintage sound engine: SP-1200 character (refined against a real SP-1200), ASR-10 Boost weight, and rebuilt S950-style Butterworth filtering on every channel.
- Loop sync, stretch, and smarter chopping: new formant-preserving timestretching engine, transient-aware trim navigation, autochop with safe boundaries, and six new audio formats.
- Meiji Sampler Radio: three live 24/7 stations — Drums, Originals, and Originals II — usable as in-app sample sources or online at radio.meiji.industries.
- Production workflow polish: tabbed Settings with project management, tap tempo, linked pad triggers, choke groups, per-channel playback overrides, vim-style navigation.
MIDI Controller Performance
Meiji Sampler now has a full MIDI mapping workflow. External controllers can behave like a physical performance surface for the terminal sampler, so you can keep the speed of keyboard-first production while playing pads, chops, loops, scenes, transport, and mixer mutes from hardware. The MIDI tab includes a MIDI Learn flow, a built-in MIDI Monitor for identifying devices and inspecting incoming events in real time, and mapping management. Move a control, choose the action, confirm the mapping, and keep building. You can map:- pad triggers and individual chop slices
- loop slot actions, mute, solo, undo, and clear
- scene trigger, cue, and stop behavior
- mixer channel mute actions
- transport play/stop and record/overdub independently
Splice Support
Sign in with a Splice account and browse Splice’s growing library of over 2 million royalty-free loops & samples without leaving Meiji Sampler. Open the Splice browser, search with natural-language queries and filters, preview results, then pressEnter to license and download a sound with a single keypress — full quality, straight into a channel. Licensed files are stored locally by Splice sample id with a license sidecar, so the same sound can be loaded again without re-licensing.
The Splice browser also received a richer browse experience and better post-download flow. When a licensed sound loads, Meiji Sampler can take you straight into Trim so you can start shaping it immediately.

Official Documentation
Meiji Sampler now has official documentation at docs.sampler.meiji.industries. The docs are built around real user intent rather than a feature dump:- Start Here for installation, setup, and first sound
- Learn for the core Browse → Assign → Loop → Scene → Mix workflow
- Guides for deeper feature areas
- Recipes for common production tasks
- Reference for shortcuts, settings, effects, paths, MIDI, and formats
- Troubleshooting for audio, files, recording, Splice, MIDI, and performance
- Release Notes for version-specific changes and upgrade guidance
Vintage Sound Engine
1.0.0 adds a deeper character layer for producers who want classic sampler color without leaving the terminal.SP1200
SP1200 is the headline sound feature in this release. Each channel can run through an SP-1200-inspired DSP chain with 12-bit crunch, 26.04 kHz converter behavior, tape-style saturation, and selectable output styles modeled after the original machine’s output character. The available SP1200 styles cover raw unfiltered grit (outputs 7 & 8), dynamic VCF behavior for transient snap (1 & 2), darker low-pass output for kicks and bass (3 & 4), and gentler filtering for melodic material (5 & 6). SP1200 sits after pitch in the signal chain so aliasing and quantization respond to pitched content, just like the real hardware.ASR-10 Boost
ASR-10 Boost adds a per-channel Ensoniq-style weight control with Lo, Mid, and Hi levels. It combines saturation, limiting, and output filtering to push drums, bass, and chops forward without requiring a separate effects chain.S950 Filter Improvements
The HPF and LPF were rebuilt as S950-style Butterworth filters with the correct steep 36 dB/octave behavior, flatter passband response, smoother cutoff changes, and better PerformFX filter response. The result is cleaner carving when you want precision and stronger vintage filter behavior when you want movement.

Long samples are much easier to turn into playable material, and stretched material now sounds dramatically better.New timestretching engine
The time-stretch engine has been replaced with a formant-preserving spectral stretcher. Melodic and vocal content survives stretching with their character intact instead of getting smeared by the older engine. Synced chop stretch reuse eliminates redundant computation, and stem playback now applies time-stretching correctly alongside the rest of the channel.Intelligent Transient Snap
The trim view now snaps the playhead to detected transients with subtle ghost markers, color-coded by frequency band so low hits, midrange attacks, and high-frequency details are easy to scan. UseShift+[ and Shift+] (or legacy { and }) to walk between snaps, b to filter by band, and < and > to adjust strictness. Snap targets are refined toward nearby zero crossings to reduce click risk. Press a to autochop the first ten accepted markers to 1-9,0.
Safer chopping workflow
Chops and trim points snap to safe playback boundaries automatically. Confirm-before-replace protects existing autochops. Channel Detail gained sample offset controls and inline sample actions so you can manage assigned audio without leaving context.Six new audio formats
The decode pipeline now reads MP3, AAC/M4A, FLAC, OGG/Vorbis, ALAC, and CAF in addition to WAV and AIFF. Read next: Chopping And Slicing, Per-Channel Playback, and Time-Stretch A Loop To Tempo.Meiji Sampler Radio
Three new Meiji Sampler internet radio stations, all live 24/7, that double as sample sources inside the app — perfect for inspiration and quick ideation:- Drums
- Originals
- Originals II
Workflow Enhancements
1.0.0 also includes a long list of production workflow improvements that make daily use smoother:- Dedicated Settings tab with project, audio, addons, and general categories
- Project tempo control with manual BPM override and tap tempo
- Per-channel playback settings for linked or copied loop, trim, chop, chop-gate, and scene-end behavior
- Linked pad triggers for layered sounds from one source trigger
- Choke groups for hi-hats, mutually exclusive chops, and one-at-a-time sample groups
- Sample Offset for small timing delays between layered sounds
- Row-aware transport behavior for pads, loops, and scenes
- Vim-style navigation with
h,j,k, andl - Caps Lock detection with an in-app warning when keyboard state can affect shortcuts
- Settings source availability so unavailable sources are easier to understand
- Random colors for loaded audio sources for easier visual scanning
Recording, Export, And Source Support
Recording review now includes peak normalization, so quiet takes can be boosted before you keep them. Bounce export now supports configurable WAV bit depth with 16-bit, 24-bit, and 32-bit float options. Source format support also expanded in the audio engine to include MP3, AAC/M4A, FLAC, OGG/Vorbis, ALAC, and CAF in addition to WAV and AIFF-family files.

- Windows installer, font, and development build fixes
- Linux and Windows development workflow improvements
- Lower macOS deployment target to macOS 11.0
- Faster local test workflows and broader automated coverage
Stability And Fixes
This release includes many stability fixes across playback, trim, chop, stretch, loops, Splice, settings, and platform builds. Notable areas include:- more reliable loop start timing and playback event delivery
- fixed stretched loop edges and synced chop stretch reuse
- fixed chop playback with timestretching
- better transient marker placement and first-marker autochop behavior
- safer trim discard and autochop replacement confirmation
- preserved downloaded samples when URL cache entries expire
- fixed Windows ARM64 stretch and Demucs build paths
- expanded unit and integration test coverage
Upgrade Notes
Most users can upgrade directly. There are a few workflow changes worth knowing:- Vim-style navigation moved some older single-key shortcuts to shifted alternatives.
- Settings is now a top-level tab and project operations live there.
- Some PerformFX feature flags were removed, so unsupported F-key bindings are cleaned up automatically.
- The stretch cache schema changed. Old cache files are purged automatically and regenerated as needed.
- Splice downloads now require signing in with a Splice account and are stored with the rest of Meiji Sampler’s local audio assets.
